--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-05-21 19:26:32 UTC --- Essentially the problem is that check_narrowing doesn't know how to handle type conversion operators or anything more sophisticated than just scalars as init and gives up. The issue should be therefore fixable relatively easily by way of perform_implicit_conversion of perform_implicit_conversion_flag but one must be careful with designated initializers, scalars which can't be initialized with a brace-enclosed initializer in C++98, special cases, otherwise reshape_init doesn't do much in case of SCALAR_TYPE_P (type).
